Tips
Below are some tips to help with the use of mortar:
• Do not guess quantities, always measure accurately
• Always mix ingredients dry before adding water to ensure
mortar
• Ensure mortar is not too sloppy, this can run causing
staining of bricks/blocks/pavers
• If dry cement becomes wet or lumpy and lumps do not break up
discard it immediately
• Do not use mortar when very hot and humid
• Keep all ingredients clean and uncontaminated from soil etc
• Mix mortar with clean water
• Do not add extra water to a prepared mix, this weakens the mix
• Keep a tarpaulin handy to cover work in case of inclement
weather
• Do not add fish or plants to a pond where the mortar mix has
not had the lime flushed with 3 water changes and 12 weeks
waiting time
